Public register

The public register of drinking water supplies in Aotearoa New Zealand.

Taumata Arowai Public Register

Our Public Register of Drinking Water Supplies includes some of the information that registered drinking water suppliers provide to us about their supplies. You can search and find the drinking water supplies in your local area in the public register.

Some drinking water supplies may not yet appear on the public register as we’re still working to confirm details of some of the almost 2,000 supplies that were transferred to us from the Ministry of Health. 

Search the Taumata Arowai Public Register of Drinking Water Supplies.

Ministry of Health Public Register

The public register from the Ministry of Health was transferred to Taumata Arowai when we became the water services regulator on 15 November 2021. This register will no longer be updated.
